Most Obese Humans are Deficient in Leptin

Question

Most obese humans are deficient in leptin.

Accepted Answer

Leptin is a hormone produced by fat cells that helps to regulate body weight by suppressing appetite and increasing energy expenditure. Obese individuals often have high levels of leptin, but their bodies become resistant to its effects, leading to increased appetite and decreased energy expenditure. Therefore, most obese individuals have high levels of leptin rather than a deficiency.
